Ask a practice manager how many visits were billed last month and the answer is usually the number of claims. Ask how many patients were seen and the answer is the number on the schedule. Those two numbers are rarely compared, and the gap between them is money the practice earned and never asked for.
In our audit work the gap is almost never zero. In a typical independent practice it sits between one and three percent of visits. In practices with paper superbills, a provider who signs notes late, or a billing hand-off that changed recently, we have seen it above five percent. At an average charge of $150 per visit and 1,500 visits per month, three percent is $6,750 of charges every month that never reached a payer. Over a year that is more than $80,000, and unlike a denial, nobody is working it, because nobody can see it.
This article is about that invisible category: where it comes from, how to measure it with reports you already have, and the two weekly reconciliations that keep it near zero.
Key takeaways
- An unbilled encounter is a completed visit with no accepted claim. It never appears in a denial queue or an AR report, so it has to be found by comparing the schedule with the claims.
- Encounters disappear at four steps: unsigned notes, charges never entered, charges held and never worked, and clearinghouse rejections never resubmitted.
- Three reports for the same 90-day window (arrived appointments, signed encounters, accepted claims) tell you the size of the gap and which step is responsible.
- Two weekly reconciliations, schedule to encounter and encounter to claim, catch almost all of it. Weekly matters; monthly lists are too long to act on.
- Past the payer's timely filing limit there is usually no remedy, which is why the rhythm matters more than a one-time cleanup.
What "unbilled encounter" actually means
An unbilled encounter is a patient visit that was completed (the patient was seen and a service was rendered) but for which no claim was accepted by a payer within a reasonable time. It is different from a denied claim, which at least exists and can be appealed, and from a rejected claim, which was sent and bounced at the clearinghouse. The unbilled encounter is invisible because nothing in the billing system points at it. The only place it exists is the schedule and the chart.
That is why the usual revenue cycle dashboards miss it. Days in AR, denial rate and net collection rate are all calculated from claims that exist. A practice can have excellent numbers on every one of them and still be losing two percent of its visits before a claim is ever created.
The four places encounters disappear
1. The visit was seen but the note was never signed
The provider roomed the patient, documented most of the note and moved on. The note sits unsigned. Most practice management systems will not create a charge from an unsigned encounter, and most providers do not receive a daily list of what they left open. Ten unsigned notes a week is five hundred a year. In electronic systems this is the single most common source of unbilled work, and it is also the easiest to fix because the report already exists in every EHR we have worked in.
2. The note was signed but the charge was never entered
In practices that still use paper superbills or manual charge entry, the superbill is the only link between the visit and the claim. If it is misplaced, entered against the wrong patient, or left in a folder over a holiday weekend, the charge never exists. Practices that moved to electronic charge capture are not immune: an order set that does not map to a CPT code, or a procedure performed by a nurse without a charge trigger, produces the same result. Injections, in-office labs and supplies are the usual casualties.
3. The charge was entered but held
Billing systems hold charges for a reason: a missing diagnosis, an inactive insurance, a provider not yet enrolled with the payer, a missing referral number. Hold queues are useful only if someone works them every day. A hold queue that nobody owns is a graveyard, and the charges in it age toward the timely filing limit while everyone assumes they are "in billing".
4. The claim was created but rejected before it reached the payer
A clearinghouse rejection is not a denial. The payer never saw the claim. Rejected claims must be corrected and resubmitted, and if nobody reviews the rejection report every day they age quietly. Commercial payers commonly allow 90 to 180 days from the date of service; Medicare allows twelve months. A rejection that sits for four months at a payer with a 90-day limit is a write-off.
How to measure the gap in your own practice
You do not need new software. Pull three reports for the same 90-day window: appointments marked arrived or completed, encounters with a signed note, and claims with a payer acceptance (an accepted 277 acknowledgment or an ERA). Count each and compare:
| Comparison | What the difference means | Who fixes it |
|---|---|---|
| Arrived appointments minus signed encounters | Visits with no documentation closed (unsigned or missing notes) | Providers |
| Signed encounters minus charges | Documented visits with no charge captured | Coding or charge entry |
| Charges minus accepted claims | Charges stuck in holds, rejected at the clearinghouse, or never submitted | Billing team, front desk for eligibility holds |
Exclude non-billable visit types (nurse-only visits under a global period, no-charge follow-ups, courtesy visits) before comparing, or the numbers will look worse than they are and the exercise loses credibility with the providers. What remains is your leakage, and the report tells you which of the four steps is responsible.
A worked example. A four-provider practice pulls the three reports for April through June. Arrived appointments: 5,860. Signed encounters: 5,791. Charges: 5,770. Accepted claims: 5,702. After removing 48 nurse-only and courtesy visits, the gaps are 21 unsigned notes (18 of them belonging to one provider), 21 signed visits with no charge (all in-office injections given by a medical assistant without a charge trigger), and 68 charges with no accepted claim (41 held for a missing referral, 27 rejected for an invalid subscriber ID and never resubmitted). That is 110 billable visits, about 1.9 percent, and every one of them now has a name next to it.
Two reconciliations that catch almost all of it
Schedule to encounter. Every appointment marked arrived or completed should have a signed encounter. Run the list of arrived appointments without a signed note and send it to each provider on Monday morning, sorted by date. Keep the list short by running it weekly, not monthly. Providers respond to a list of eight notes; they ignore a list of eighty.
Encounter to claim. Every signed encounter with billable services should have a charge and a claim with a payer acceptance. Run the list of signed encounters without an accepted claim, sort by date of service so the oldest are worked first, and assign each line to the person who can fix it: the coder for encounters awaiting codes, the biller for held charges, the front desk for eligibility and referral problems.
The first time a practice runs these two reports the results are uncomfortable. That is the point. After a few weeks the lists shrink to a handful of items, and those items are usually a process problem you can fix once: a charge trigger added to the injection order set, a referral field made mandatory at scheduling, a same-day signing rule for one provider.
Four numbers to keep on the wall
- Unsigned encounters older than 3 days, by provider.
- Signed encounters without a claim older than 5 days.
- Claims rejected and not resubmitted within 2 business days.
- Charge lag: days from date of service to claim submission, as a median and a 90th percentile.
A practice that keeps these four numbers visible rarely loses encounters. The ones that do are almost always the ones where nobody is assigned to look. We think the 90th percentile of charge lag is the most underused of the four: a median of two days looks healthy while forty encounters sit at day 60, and the median will never show them.
Questions we hear
How much charge lag is acceptable?
A median of two to three days from date of service to claim submission is achievable for office visits when notes are signed the same day. Procedures that depend on an operative report or a pathology result take longer. Watch the 90th percentile as well as the median; a good median can hide a tail of encounters that are weeks old.
Can we recover encounters that are already past timely filing?
Some payers accept a timely filing appeal with proof that the claim was originally submitted on time, such as a clearinghouse acceptance report. For encounters that were never submitted, there is usually no remedy except with the patient, and most practices choose not to bill patients months after a visit. This is why the weekly rhythm matters more than a one-time cleanup.
Who should own the reconciliation?
One person, usually the billing lead or practice manager, runs the two reports every week and distributes the lists. Providers own unsigned notes. The billing team owns everything after the signature. If you want an outside pair of eyes first, the Revelrex RCM Audit starts with exactly these reconciliations for the last 90 days, and when Revelrex handles medical billing the schedule-to-claim reconciliation runs weekly as part of the service.
What to do this week
- Pull arrived appointments, signed encounters and accepted claims for the same 90-day window, by date of service, and write down the three counts.
- Remove non-billable visit types and put a dollar figure on the remaining gap using your average charge per visit.
- Send each provider their list of unsigned notes older than three days, sorted by date, and agree a same-day signing rule.
- Assign every held charge and every unworked rejection to a named person, oldest date of service first, and check each against the payer's filing limit.
- Put the two reconciliations on the calendar for the same morning every week, with one owner, and add the four wall numbers to your monthly report.
